I have the HAT Dac+ Pro and am attempting to install on a Pi4 B with Raspbian. it is all connected up and should be ready to go. Plugged into the amp and thought I would test just with a video online as I thought it would be recognised by Raspbian. So far, nothing has happened... no sound.
I know I could install with the HifiBerry OS but I wanted to use this with my current Raspberry PI. I thought i would be recognised.
What am I likely to be doing wrong and are there instructions anywhere regarding checking the setup in Raspbian?
